Après des études supérieures à l’Ecole Normale Supérieure et l’obtention de l’Agrégation de Chimie en 2010, j’ai soutenu une thèse en 2015 à Sorbonne Universités (Paris) sous la direction d’Hélène Pernot et Eric Marceau, en collaboration avec IFP Energies nouvelles. Le sujet de ma thèse porte sur la transformation d’alcools biosourcés catalysée par des solides acido-basiques comme l’alumine γ par approches mixtes expériences-théorie. J’ai ensuite effectué un séjour postdoctoral à l’ETH Zürich dans le groupe de Christophe Copéret où j’ai travaillé sur deux réactions catalysées de conversion du dioxyde de carbone : synthèse du méthanol et reformage du méthane à sec.
Depuis 2018, je travaille comme chercheur à IFP Energies nouvelles sur des projets de recherche fondamentale comme appliquée dans le domaine du recyclage des plastiques ou de la conversion des sucres issus de la biomasse en bioproduits. Mes travaux combinent des approches expérimentales (catalyse, spectroscopie RMN ou XAS) et des approches par chimie théorique (Théorie de la Fonctionnelle de la Densité, DFT).
Mes travaux ont été valorisés par 38 publications et 15 brevets, et leur contribution a été récompensée par 3 prix : le Prix Louis Armand 2017 de l’Académie des Sciences, le Prix de la Jeune Recherche de la ville et métropole de Lyon 2023, et le Prix Jeune Chercheur de la Division Catalyse de la SCF 2025. Par ailleurs, je suis co-inventeur de brevets qui donnent actuellement lieu à des applications à l’échelle industrielle.
Je prépare actuellement mon Habilitation à Diriger des Recherches, que j’ambitionne de soutenir en septembre 2025.
Since 2021, I am Principal Investigator of the French Research National Agency (ANR) project SELECTOSZE (ANR-21-CE07-0043-01), carried out at IFPEN. This project ambitions to understand the factors that drive the selectivity in the transformation of biomass-based sugars (glucose, fructose, xylose) catalyzed by Lewis-acid zeolites M-β, where M is a tetravalent metal ion inserted in framework position (M = Sn, Ti, Zr, Hf). Such materials have proven to be efficient for the isomerization of glucose into fructose, but they can also catalyze other reactions, such as the retro-aldolization of sugars, which is a key step for the formation of short-chain chemicals from sugars, such as lactic acid or ethylene glycol.
The project encompasses catalyst synthesis actions, catalytic reactions including mechanistic studies, resorting to isotopic labelling experiments, DFT calculations, which aimed at (i) describing accurately the speciation of the Sn sites in different operating conditions (ii) realizing a mechanistic study of the conversion of sugars.
